고용형태 및 기업 유형에 따른 근로자 임금분석 : 성향점수 매칭과 이중차분 분석 = Analysis of Worker Wages by Employment Type and Company Type : Focusing on PSM-DID

다국어 초록 (Multilingual Abstract)

This study uses data from the 24th year of the Korean Labor and Income Panel Study(KLIPS), which is conducted annually by the Korea Labor Institute. We examined the effects of worker's employment type and company type on wages. The dependent variable was analyzed by log-transforming monthly salary data. The independent variables were regular and non-regular worker types and eight types of companies. The control variables were gender, age, unionization, union membership and education. When analyzing the eight types of companies, we found that men were paid more than women. Unionized workers earned more than non-unionized workers. In terms of education, PhDs were paid more than non-unionized workers, regardless of whether they were full-time or part-time. When analyzed by workplace location, metropolitan areas paid more than non-metropolitan areas. Propensity score matching and double difference analysis showed a -0.174 difference between unionized and non-unionized temporary workers. Therefore, in order to close the wage gap between regular and non-regular workers, we need to create jobs that are equivalent to regular jobs. Long-term policies are needed to ease the divide between regular and non-regular workers by expanding opportunities for self-development and vocational training for non-regular workers.
